Saxon » SaxonC

As reported in https://stackoverflow.com/questions/71362331/saxon-c-he-11-2-prints-empty-output-when-xslt-has-an-include-or-using-xslresu, SaxonC 11.2 HE fails to compile a stylesheet using regular expressions and Unicode categories. Saxon C 11.2 EE, on the other hand, compiles and executes the code fine, so I presume that due to a build problem, the SaxonC HE release does not have the categories.xml or does not look in the right place.

Simple stylesheet that does not work with HE:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  version="3.0"
  xmlns:xs="http://www.w3.org/2001/XMLSchema"
  exclude-result-prefixes="#all"
  expand-text="yes">

  <xsl:template name="xsl:initial-template">
    <test>{replace('abc12def', '\d' , '')}</test>
  </xsl:template>

</xsl:stylesheet>

When I run that with transform -t -it the output for HE is only

SaxonC-HE 11.2 from Saxonica
Java version 1.8.0_181

so it fails during compilation, meanwhile EE outputs

SaxonC-EE 11.2 from Saxonica
Java version 1.8.0_181
Stylesheet compilation time: 54.4433ms
Processing  (no source document) initial template = xsl:initial-template
<?xml version="1.0" encoding="UTF-8"?><test>abcdef</test>Execution time: 2.074ms
Memory used: 13Mb

Looking at the error output from stylesheet compilation with HE the stack trace shows

so that clearly indicates that compilation fails as categories.xml can't be found.
